Blanche was one of the greatest leaders of the Outworld army alongside with General Shao. and she was the master and raised Li Mei.
In my fan story. After the ending of MK11 Aftermath, new warriors and evils are rising for a new menace that wants to take by force Earthrealm and Outworld, breaking the new accords stablished by commander Reiko.
Blanche was one of the most strongest leaders of the Outworld army with General Shao. Now that Shao is in charge now of the army and commander Reiko has stablished the new accords. There's a new menace that wants to take the realm of Outworld and conquer. The Dragon King known as Onaga.
After Blanche was retired, but not by her own, but "forced" by the new clone of Kitana Kahn (created in secret by Shang Tsung) and mistress of commander Reiko. she was falsely accused for traitor to her empresses and she escape from General Shao and commander Reiko militaries.
I guess everyone knows lol. she's based on the NPC in the stage of MKX, Outworld Marketplace, named Blanche. also she's evenly inspired by the boss from Sekiro, Lady Butterfly.
Also, her story was inspired a little and connected with the story of the concept art of Reiko and the new clone of Kitana by one of my favourite artists John Dimayuga.
